PATENT ELASTIC SOCKET FOR PEN-HOLDERS.

SPECIFICATION forming part of Letters Patent- No. 413,092, dated October 15, 1889.

Application fikd March 2 9 l 8 8 8.

.To all whom) it may concern..-

Be it known that I, MICHAEL I. RODRIGUE, a citizen of the United States, residing in the city and county of San Francisco, in the State of California, have invented certain new and useful Improvements in Elastic Sockets for Pen-Holders; and I do hereby declare that the following is a full, clear, and exact description of my said invention, reference being had to the drawings that accompany and form part of this specification.

My invention relates to improvements in grips or sockets for fixing pen-points to handles or holders; and it consists in the production of a socket capable of adjusting itself to different sizes and shapes of pelrpoints, and of clamping or holding the same firmly, and also possessing the property of imparting a certain elasticity to the pen-point when in use.

The nature of my said improvements and the manner in which I proceed to construct and produce my elastic socket for pen-holders are fully explained in and by the following description, reference being had to the accompanying drawings by letters and figures.

Figure 1 represents the complete socket and holder with the pen-point set ready for use. 2 shows the socket with the softrubber sleeve taken off. Fig. 3 is a view of the socket complete, but with the soft-rubber part broken away. Figs. 4 and 5 show the inner or metallic part of the grip. Fig. 6 is a sectional View through the butt-end of the stock or handle before the grip is fitted to it. Fig. 7 is the softrubber sleeve or outer part of the grip.

Similar letters of reference indicate like parts in all the figures of the drawings.

This improved socket for pen-point is composed of an inner split sleeve or barrel of metal, and an outer and surrounding tube of soft rubber fitting closely over the metal part, and, by virtue of its elastic qualities, compressing or drawing the metal sleeve to gether upon the wooden portion or stock of the holder, the end portion of the holder be ing turned oil of cylindrical shape and of suitable diameter to take the metal. sleeve.

sheet brass or other material having sufficient spring and stiifness to maintain its shape by bending a strip of suitable widthand length around a mandrel, or by cutting it from a length of tubing. Slits a a are made at one end running longitudinally toward the other end of the sleeve, and one of them is carried the full length, so that it divides the tube from end to end. The butt-end of the stock or handle port-ion C is turned down to a smaller diameter and of suitable thickness to take the metal-sleeve, these two parts be ing so proportioned that the metal fits closely The part B, fitting over and surrounding this sleeve, is made of soft-rubber tubing, such as can readily be obtained of the manufacturer at the present time of various sizes and degrees of thickness. Tubing of one-fourth to threeeighths inch in diameter will be found to answer Well for this sleeve. This rubber tube should be of such diameter internally that when drawn over the metal part A it is stretched, and by its contraction is made to draw the metal part together around the stock. When properly formed and fixed, the surface ofthe elastic socket and the body of the handle should come flush with each other, and when properly made, also, the socket will retain its place on the handle without requiring any additional fastening; but a metal band, as X, fixed over the joint where the rubber sleeve and the wood come together will add to the elegance of the holder, and may also be made to confine the rubber at this point by being slightly pressed over it. In setting the pen-point in this holder, it is inserted between the metal jaws of the grip, with the nib or point in line with the long slit of the sleeve, and the shank of the pen is pressed down into the socket a sufficient distance to hold it. In this position. the pen-point is gripped firmly, but not rigidly, and while it is held against any tendency to move laterally it is permitted to have a certain amount of elasticity under vertical pressure. hen inserted in this manner under the metal sleeve, the pen-point is gripped with sufficient degree of force by the contraction of the surrounding rubber; but its own inherent elasticity is not taken away or restricted, so that the normal flexibility of the nibs and other qualities of pen-points, even of the finest kinds or grades, are not alfected. The same size of socket will take in and properly hold any size and quality of pen-point, and, besides holding it always in perfect alignment with the handle, the elastic properties of the socket impart a considerable degree of flexibility to the pen and allow a freedom of action that renders the pen quite sensitive to the pressure and motions of the fingers. Under side movements and angular movements of the hand of the writer the pen-point will have no slip or loose motion; but under direct perpendicular or downward pressure it has the quality of yielding.

In addition to the above-mentioned qualities and properties that contribute to the comfort of the writer and the elegance of handwriting, my improved socket possesses 20 the advantages of low cost of manufacture and great durability.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent is In a pen-holder, the combination, with the butt or handle portion O of the stock, of a split sleeve A, of metal, surrounding the portion 0, to receive the pen between it and said portion, and a soft-rubber tube B, surrounding and clamping the sleeve 0, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.

MICHAEL I. RODRIGUE. [L. s]
